Abstract: The present invention is an acoustic cabinet for the storage of musical instruments. Acoustic cabinet can have a storage portion having a plurality of individual storage units contained therein. One or more grill doors can cover the open end of acoustic cabinet. The size, shape, and arrangement of grill bars of door can be configured to reduce the effect of resonance. Rear panel of acoustic cabinet can include one or more sound-absorbing panels that absorb sound as it passes through acoustic cabinet. A protective backing can also be disposed between sound-absorbing panels and individual storage spaces to protect the panels from damage when instruments and other objects are inserted into the storage spaces. A combination of a grill door and sound-absorbing panels can allow acoustic cabinet to have a net-absorptive effect on a rehearsal room. One or more acoustic cabinets can be strategically positioned throughout a rehearsal room for optimal acoustic performance.
